微型仿生声探测阵列集成设计及实验验证

Integrated Design of Miniature Biomimetic Acoustic Detection Array and Experiment

微型仿生声探测技术在军事领域主要用于目标的定位,本文通过软硬件两个方面对微型仿生声探测阵列进行了集成设计,硬件包括模拟信号获取模块,软件包括模数转换控制模块,采用的MEMS传声器为微传声器,选取的放大器为AD620.通过使用ADC驱动程序与数据采集处理程序对实验数据进行了采集,分析所得实验数据得出随着传声器组间的间距b值的减小,A/D转换的时间必须要减小,这样才能保证传声器的定位所得到的数据值保持在一定的精度范围内.

Miniature biomimetic acoustic detection technology was used mainly for the location of the target.We performed an integrated design for the miniature biomimetic acoustic detection array from hardware and software.The hardware included an analog data gaining module,and the software included AD transferring part.We took MSMAS42z as the microphone and selected AD620 as the amplifier.The experiment data were collected by using ADC driving program and data collection-processing program.The experimental results show that with the distance between the groups of microphone descending,the A/D data transferring time must be decreased in order to ensure the location data within a certain precision range
